The site where I bought my copy from just sent me the following info/instructions for getting the ball rolling on a replacement vinyl when they are pressed:
You may have heard by now Sacred Bones screwed up. We are being told to contact our customers concerning a replacement. We've pasted replacement instructions and the message we received from our distributor concerning the repress issue. Please follow instruction A below to obtain your replacement. If you need further assistance please fee free to contact us.
Replacement Instructions: A. Customers who purchased the record online or have their receipt from a brick and mortar store handy may email Brad Sanders / firstname.lastname@example.org a copy of their receipt and Sacred Bones will ship them a replacement copy when the pressing is complete. Message from our distributor: The audio contained on the 12" pressing of 'Halloween Theme (Remix)' released on Sacred Bones is a previous recording of the Trent Reznor & Atticus Ross version of the song, which differs from what was released digitally last year. A lacquer of the 'previous version' was cut and then scrapped, because Trent and Atticus decided that they could improve upon the recording. They went on to create the 'definitive' track that is available everywhere digitally. A MISTAKE WAS MADE when pressing the currently available 12", and the 'previous' version was erroneously included. To correct this unforgivable error, we are reprinting the CORRECT version and will provide it to you free of charge. We are currently working on the repress. As of now, we are expecting these to ship in early 2019 and will update you soon on the delivery timeline. As a NIN.com customer, you do not need to take any additional steps to receive your replacement copy. The replacement offer includes those who purchased from other retailers.
Just in case you hadn't heard anything from your distributor, figures I'd share.
